Hydraulics Repair and Servicing

one-stop, full service hydraulics workshop

WesTrac offers a one-stop, full-service hydraulics workshop which specialises in the repair and manufacture of large hydraulic cylinders and all associated equipment. We are one of the largest providers of this service in Australia, and the preferred choice for customers with Cat® equipment.

Improve your operation

The hydraulics are the heart of your machine, so you’ll want to keep them in 100% running order. Maintaining your hydraulics will not only improve your day-to-day operations, it will also have a direct outcome on your bottom line. Reliable and efficient hydraulics make the working day run more smoothly, and, when well-maintained, your hydraulics will help you do more in your operation.

Quality service, every time

We undertake all our work in-house and make use of our industry-leading oil and fluid sampling laboratory to ensure we meet Caterpillar’s strict contamination control standards. Our team offer exceptional support and are driven to get the job done to your satisfaction. You can trust the quality of our hydraulics services as we regularly undergo audits to ensure we meet Caterpillar’s strict quality control industry standards.

Our specially-trained, highly skilled workers are hydraulics salvage specialists. We can strip and rebuild your general mining hydraulic components to meet and exceed industry requirements. Our team can then service your machine, in terms of these requirements.

We also offer remote mine-site fixed plant rebuild maintenance. 

Save time and money

You rely on your machine’s hydraulic systems to keep your machine running at optimal levels, but, like any major component, the hydraulic system is sensitive to dirt and debris. And this can impact performance, reliability and safe operation. Keeping on top of your hydraulics repair and maintenance can save you time and money.
